... Sieburth says. Seeking the Chemical Signal To indicate what kind of hormone turned off leaf growth, Van Norman and Sieburth treated thale cress plants with tiny amounts of a herbicide named fluridone, which inhibits production of carotenoids. When they used it on mutant plants which otherwise would have...

...on. A large population of birds in a region could indicate a suitable habitat, or it could, in fact, could be the only place the animals could find, wrong for feeding, mating, and rearing young, in other words, an "ecological trap." "Ornithologists and ecologists in Europe and North America have good re...

... a time in which a variety of paleoclimate records indicate unusual warmth over much of the Northern Hemisphere. The authors of the new study argue that there are climate mechanisms involved that make warming climate conditions likely to lead to increased prevalence of drought in the western, interior region ...

...critical part of the disease process, while others indicate that they may help protect the cells from toxic proteins or that they are merely bystanders in the disease process. One problem in identifying how inclusion bodies influence disease is that researchers have been unable to track changes in indivi...

...of neurons in the lateral intraparietal region did indicate that it was involved in making those decisions. Analysis of the experiments also indicated that the neurons were encoding the relative subjective desirability of a choice, rather than absolute subjective desirability. "While we cannot ask nonhuman pr...

...ts." The researchers concluded that their findings indicate that two separate brain systems--one involving taste and one recalling cultural influence--in the prefrontal cortex interact to determine preferences....

...(fMRI), twelve healthy subjects pressed buttons to indicate whether they saw a face or a house, as images flashed on a computer monitor. Some of the images were so noisy that they were barely discernable, reducing accuracy from 95 percent to 82 percent. The researchers looked for a site in the brain's fro...

...ent to test suspicious-looking residues that could indicate the presence of explosives or drugs inside packages. But while most mass spectrometers are unwieldy, cabinet-sized machines that require samples to undergo hours of intensive preparation before testing, Cooks' team has found a way to test untreated s...

...s of a potential medicine. Frequently, the studies indicate that the drug is not really effective at all, or only for a small number of patients. At present, nothing exists for measuring whether a candidate drug is truly effective during development. Bio-markers can bridge this gap and thus substantially lowe...

...als of so-called demethylation agents, but they do indicate that careful attention should be paid to results of laboratory experiments and clinical trials that use the agents, since so many genes are affected, says Feinberg. "It was kind of assumed that removing methyl groups would turn some genes on an...

... determining whether mussels' blood chemistry will indicate when bivalves are stressed. "Right now, the mussel is either alive or dead; we can't tell how healthy it is," Neves said. "We are also studying whether the pink heelsplitter mussel is able to produce what would be the only natural purple pearls on th...

...d their peers," says Gage. "That smaller range may indicate a reduced ability to understand a complex, fast-moving human speech stream. For example, to accurately decode speech, we need to be able to tell the difference between sounds such as the 'b' in beach and the 'p' in peach. We do this without conscious...

...rcent," says Przedborski. "Overall, these findings indicate that in the MPTP mouse model, the protein COX-2 may play a role in the process that leads to the death of the cells implicated in the control of movement by interfering with the programmed cell death process." Przedborski intends to confirm this rol...

He said that an estimated 5% of women of reproductive age have endometriosis and somewhere between 15% and 19...
